YRKS series high voltage 6KV/10KV three-phase asynchronous motor (6KV center height 355~630, 10KV center height 400~630) is a wound rotor three-phase asynchronous motor. The motor is produced according to the technical conditions of JB/T10314.1-2002. This series of protection is IP44/54, and the cooling method is air-cooled IC81W.
This series of motor can provide a larger starting torque at a smaller starting current; it has the advantages of high efficiency, energy saving, low noise, low vibration, light weight, reliable performance, easy installation and maintenance.
Applicable to the feed line capacity is not enough to start the squirrel-cage rotor motor, a longer starting time and more frequent starting, speed and other occasions within a small range. Such as dragging hoists, rolling mills, wire drawing machines, etc.
1) Belting driving is not allowed on the motor of 2 poles and 4 poles.
2) Belting driving applied on the motor of other poles, should be negotiated with manufacturer.
